2.2.15.16. Check of the valve of a maslorazbryzgivayushchy nozzle

Fig. 2.161. Scheme of check of the valve of a maslorazbryzgivayushchy nozzle


Submit the compressed air to the valve of a maslorazbryzgivayushchy nozzle of A and be convinced that air passes through the valve B (fig. 2.161).
If air does not pass, replace the valve of a maslorazbryzgivayushchy nozzle.
Pressure of air: 216–274 kPas.
Piston check

ATTENTION
The piston, piston ring and rod do not understand usual practice. At piston replacement the piston finger, a piston ring and a rod are replaced together, as a uniform element.


Fig. 2.162. Measurement of diameter of the piston


Measure external diameter of each piston at right angle 90 ° to a piston finger on 10,0 mm above the piston (fig. 2.162).
If diameter of the piston – is less than norm, replace the piston, a piston finger, a piston ring and a rod assembled.
Diameter of the L8 piston:
82,965–82,995 mm;
LF, L3, L3 (with the mechanism of change of phases of a gazoraspredeleniye):
87,465–87,495 mm.
Measure a gap between the piston and the cylinder.
If value does not correspond to norm, replace the piston, a piston finger, a piston ring and a rod assembled.
Normal gap: 0,025–0,045 mm.
Maximum gap: 0,11 mm.

Fig. 2.163. Gap measurement between a piston ring and a ring flute


Measure a gap between a piston ring and a ring flute on all circle of the piston (fig. 2.163).
If the gap exceeds maximum, replace the piston, a piston finger, a piston ring and a rod assembled.
Normal gap:
the top: 0,03–0,08 mm;
the second: on 0,03–0.07 mm;
maslosjemny: 0,03–0.07 mm.
Maximum gap:
the top: 0,17 mm;
the second, maslosjemny: 0,15 mm.

Fig. 2.164. Measurement of a gap of a piston ring


Insert a piston ring into the cylinder and, pressing a ring the piston, displace it in the bottom point. Measure a gap in the lock of each piston ring shchupy (fig. 2.164).
If the gap exceeds maximum, replace the piston, a piston finger, a piston ring and a rod assembled.
Standard gap:
the top: 0,16–0,31 mm;
the second: 0,33–0,48 mm;
maslosjemny: 0,20–0,70 mm;
maximum gap: 1,0 mm.
